This EU study suggests that we could produce enough hydrogen to fuel air travel with about 32 Pwh annually, which is maybe 20% of current global energy producti

  This honestly is not a study, in the scientific sense, it's a McKinsey made scenario (and they are definitively not skilled in anything industrial, they only deal with finance) of something McKinsey want and present in nice, high paid brochures to offer politicians a way to justify spending in this or this other area. So far the very few experimental plants we have made have proven the fact that, yes, the process work on solar, eolic ec, but also the fact that producible volumes are FAR BELOW the demand, not because we do not have enough plants so far on scale, but because we can't have them on scale on Earth at the actual state of tech. Beside that so far we still completely miss the hydrogen storage issue: we can't store hydrogen in ANY known form. We can fill tanks of it, it will leak out slowly with relevant safety issues, and with the biggest issue that a just filled tank will be essentially empty in few days. People like to dream, like to deny the reality following dreams pushed by interested parties, but they are just dreams, with good outcome for some scammers for some period of time, disasters for the dreamers.
